3 electoral votes for ever

[Brittain33]

I chose everything except Delaware and South Dakota. I wrongly voted for Montana.

To have the chance for faster-than-average growth to make it into the next group, you need to not be towards the bottom of the list now (Wyoming, Vermont) and need to have at least a mid-sized urban area that could conceivably expand (ruling out North Dakota, Vermont again.) Alaska has a big city but it's constrained by geography and climate.

Montana is eligible because it's on the knife-edge now and it's possible for moderate growth to do it. 

Delaware is in the path of suburbanization and increased density and has that low tax regime so it's possible.

South Dakota has population growth and a viable metro area that is growing.

... and why?

Why does everybody think that North Dakota will be stuck, whereas some of these people give South Dakota the chance of growing?

South Dakota has both a higher current population and a faster growth rate than North Dakota.

Also, resource extraction and agriculture doesn't drive high volume population growth.
